Foreword

The text of document 13/1520/FDIS, future edition 1 of IEC 62056-9-7, prepared by IEC/TC 13 "Electrical energy measurement, tariff- and load control" was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as EN 62056-9-7:2013.

The following dates are fixed:

• latest date by which the document has to be implemented at national level by publication of an identical national standard or by endorsement

(dop) 2014-04-04

• latest date by which the national standards conflicting with the document have to be withdrawn

(dow) 2016-05-28

This document supersedes EN 62056-53:2007 (PART).

EN 62056-9-7:2013 includes the following significant technical changes with respect to EN 62056-53:2007:

Note: Whereas IEC 62056-53 Ed. 2.0 contains the specification of the DLMS/COSEM communication profiles, IEC 62056-5-3 Ed.1.0 replacing the earlier edition does not.

• The title of the standard has been aligned with the title of other parts of the revised IEC 62056 series;

• Clause 4, Targeted communication environments has been extended, a functional reference architecture figure has been added;

• Clause 5, The structure of the profile(s) has been extended, the Figure has been generalized and simplified;

• In clause 6, Identification and addressing scheme, the port number assigned by the IANA for DLMS/COSEM has been added;

• In subclause 9.1, Two paragraphs specifying how confirmed and unconfirmed COSEM-OPEN and xDLMS service invocations have been added;

• Subclause 9.6, Transporting long messages, has been amended. It specifies now that for transporting long messages, application layer block transfer can be used (also available now with SN referencing);

• The clause on Multi-drop configurations has been removed. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.
